REFRIGERATION CYCLE DEMONSTRATION UNIT Deluxe

The vapour compression refrigeration and heat pump cycle is of paramount importance in food and drug preservation, air conditioning, heat pumps, and other industrial and commercial processes. The efficient and safe use of refrigeration systems carries added significance given the problems of ozone depletion and global warming. It is therefore essential that students develop a thorough understanding of both the practical aspects of refrigeration and the thermodynamic processes affecting the performance of the cycle. Learn about REFRIGERATION CYCLE DEMONSTRATION UNIT price for optimal educational outcomes.. Often the most difficult concept for new students is the process of evaporation at low pressure and condensation at high pressure. By utilising a non-toxic working fluid with a low vapour pressure, the evaporation and condensation processes are clearly visible in thick-walled glass chambers.

The evaporator consists of a closed, thick-walled glass chamber containing a pool of working fluid, into which is immersed a specially treated copper coil. A hermetic compressor draws vapour from the evaporator, compresses it, and discharges it to the condenser.

The reduction in evaporator pressure causes the refrigerant to boil, extracting heat from the water flowing through the coil and generating more vapour for the compressor. From the compressor, the high-pressure vapour passes to the condenser — of similar construction to the evaporator — which contains a nickel-plated water-cooled copper coil.

Vapour condenses on the surface of the coil and falls to the bottom of the chamber, transferring heat to the cooling water flowing through the coil. A float-controlled expansion valve at the base of the condenser chamber controls the flow of high-pressure refrigerant liquid returning to the evaporator.

After passing through the expansion valve, the refrigerant expands to form a liquid-vapour mixture at evaporator pressure and the cycle repeats. Standard instrumentation enables measurement of condenser and evaporator pressures and temperatures, water flow rates, and water temperatures.

Condensing and evaporating pressures are varied by adjusting the water flow rate to the evaporator and condenser coils using integral control valves on individual flowmeters.
